Vapor intrusion a concern at toxic spill sites

Vapor intrusion can happen in any home.
The United States Environmental Protection Agency (EPA) warned last week that 10 homes in the Phoenix area of a polluted toxic spill site had concerning levels of chemicals indoors.

The original source of the pollution is a former Motorola plant that accidentally leaked chemicals (including trichloroethylene, or TCE) from industrial solvents into the ground in the 1980s.

TCE is a known carcinogen and scientists say it could be harmful even at relatively low concentrations.

The EPA and others are monitoring the levels of chemicals in the area, but last year, they measured for the first time the ambient air inside nearby homes to check for vapor intrusion.

Vapor intrusion is what happens when chemicals and gases from contaminated groundwater and land enter homes through cracks and fissures in the foundation or building. Once inside the home, they can build up and become an even bigger health hazard.

The homes that measured concerning levels of TCE will be equipped with special machines, which circulate outdoor air inside the home and prevent vapor intrusion by utilizing pressure.

Clean the air with portable air cleaners

An industrial-strength air cleaner with many pounds of activated carbon and HEPA as well as other filters can help keep the ambient air clean and prevent a buildup of toxic substances.

Activated carbon is one of the safest and most trusted filter media for the removal of airborne chemicals, gases, fumes and odors (including VOCs such as formaldehyde, benzene, toluene, trichloroethylene and more).

With other filters like HEPA and UV, the air cleaners also remove airborne particles, dust, bacteria, viruses and mold.

Electrocorp offers air cleaners for environmental consultants (to be used in single and double-family homes at certain Superfund sites) as well as air cleaners for a wide range of industrial and commercial applications.
